YOU Pei-qing, WEN Rui-ming, DENG Zhong-ri, YU Shan-xin (Hunan City College, Yiyang 413000, China)  
Benzoic esters were synthesized using sodium bisulfate monohydrate as a catalyst from benzoic acid and various alcohols. The reaction conditions were as follows: benzoic acid 50mmol, n(benzoic acid) ∶n(alcohol) ∶n(sodium bisulfate)=1 ∶3(or 4) ∶0.2, reaction time 2h. The benzoic esters was characterized by elementary analysis, IR and 1H NMR.
